Simple hashing problem
Webb4 maj 2024 · In simple terms, hashing means taking an input string of any length and giving out an output of a fixed length. In the context of cryptocurrencies like bitcoin, the transactions are taken as input and run through a hashing algorithm ( bitcoin uses SHA-256) which gives an output of a fixed length. Let’s see how the hashing process works. WebbNiceHash is an open marketplace that connects sellers or miners of hashing power with buyers of hashing power. Buyers select the crypto-currency that they want to mine, a pool on which they want to mine, set the price that they are willing to pay for it, and place the order. This order is then forwarded to everyone who is connected to NiceHash ...

Webb29 sep. 2010 · Let say we have a hash function f (id) ,that takes above ids and creates hashes from it . Assume we have 3 servers - (s1 , s2 and s3) We can do a modulo of hash by the no of servers ie 3 , to map each each key to a server and we are left with following. We could retrieve the value for a key by simple lookup using f ().
